MICROGREEN BUSINESS GUIDE · NEW BRUNSWICK, NJ

Start a microgreen business in New Brunswick, NJ.

Most New Brunswick kitchens serving microgreens are split between out-of-town distributors and a handful of local growers stretched thin. The chef-driven restaurants around George Street and the campus-adjacent concepts at Rutgers are mostly buying greens trucked in by distributors. The New Brunswick grower who fixes that gets first crack at every account in the city.

Quick Answer

You can start a microgreen business in New Brunswick with under $400 in initial equipment and grow it into a $2,500 to $6,500 per month side income within 90 days. Here is the local demand picture, the unit economics at Middlesex County wholesale prices, and the operating system used by the working microgreen farms.

Walk into five chef-driven restaurants near the Rutgers campus on a Tuesday and ask where the microgreens come from. How often is the answer a New Jersey grower instead of a national distributor?

What New Brunswick buys today

New Brunswick is the home of Rutgers University and one of the most diverse food cultures in central New Jersey, with a Hungarian American food tradition in the city's historic European district, a strong Latin American presence, and a growing chef-driven downtown scene. The Rutgers campus drives a sophisticated cafe and brunch economy alongside steady catering volume.

The Robert Wood Johnson University Hospital and the Johnson and Johnson corporate presence anchor a major institutional catering economy that runs through fresh produce fast. The State Theatre and the downtown event venues support a meaningful weekend dining economy. Seasonal farmers markets round out direct-to-consumer demand.

For indoor growing, New Brunswick faces humid summers and cold winters typical of central New Jersey. A basement, garage, or spare bedroom with a small dehumidifier and window AC holds the 65 to 75 degree microgreen window year round, and once that is dialed in the climate is not a constraint.

Every week you wait, another George Street kitchen signs a long-term deal with a distributor route. What does it cost you when the chef-driven and institutional accounts you wanted are already on someone else's invoice?

The math, in New Brunswick prices

Middlesex County wholesale microgreen prices run at the mid metro tier, with chef-driven and institutional catering accounts paying premium for cut-to-order local product. Here is what the unit economics look like at conservative New Brunswick numbers.

Startup cost

$400

Trays, soil, seed, lights. Used gear cuts this in half.

Per-tray net

$20-$30

After seed, soil, packaging, delivery.

Trays per week

100

Target for $3K-$5K/mo at New Brunswick pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in New Brunswick square footage

A 10 by 10 foot room with two vertical shelving units holds 60 to 80 active trays. That is enough to produce $3,000 to $5,000 per month in New Brunswick at standard wholesale prices. A two-car garage doubles it. A basement triples it.

Picture the week where Sunday is planting, Tuesday is delivery on the George Street loop, Saturday is the market, and the app tells you exactly which trays to cut. What changes about how you spend your other four days when the business runs on a system?

Three things every working microgreen farm in New Brunswick runs on

  1. A seed density and watering plan you trust. The number one cause of failed trays for new growers is over- or under-seeding. The cheat sheet inside Grown Like A Pro gives you grams per 10x20, soak hours, blackout days, harvest day, and watering for sixty-one varieties.
  2. A rotation tracker. Once you are running thirty-plus trays per week, you cannot remember what is in blackout, what is in light growth, what harvests Tuesday. A spreadsheet works for the first month. After that you need a system that pings you the day before each harvest and reorders seed before you run out.
  3. A customer + invoice layer. Restaurants in New Brunswick want predictable weekly invoices and net-15 terms. Farmers market customers want clamshell tracking. Both want consistency. The app handles both.

The IKEA test

If you can follow an IKEA instruction sheet without screaming at the family, you can grow microgreens at a commercial level in New Brunswick. The steps are about that difficulty: open the box, lay out the parts, follow the picture, repeat. Trays are the bookcase. Seed is the dowels.

If you ever did struggle with the IKEA bookshelf, that is exactly why Glappy lives inside the app. Glappy is the in-app coach that breaks every step down barney style, in your own language, from "how do I plant my first tray" to "why is this tray going leggy at day five and what do I do about it tonight." Type the question, get a step-by-step answer. There is no question too basic. The whole point is that a New Brunswick grower starting today is not on their own.

What you are not buying

You are not buying a course. You are not buying a hype product. You are not buying seed from us, and you are not buying trays from us. We do not sell either. Grown Like A Pro is the operating system you run your New Brunswick farm on. The growing happens in your basement.

New Brunswick microgreen FAQ

How much can I make growing microgreens in New Brunswick?
A working microgreen farm in New Brunswick produces $3,000 to $8,000 per month within 90 days of starting. The math: 100 trays per week, $20 to $30 net revenue per tray, harvested in a basement, garage, or spare room. The ceiling is set by how many restaurants and farmers market customers you can serve, not by the growing setup.
Is it legal to sell microgreens in NJ?
Yes. In most of New Jersey, microgreens fall under the state's cottage food law for direct-to-consumer retail at farmers markets and to private customers. Restaurant wholesale typically requires a basic food handler permit. Verify with the New Jersey Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in New Brunswick?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including New Brunswick. Broccoli is the highest-margin variety because of its sulforaphane reputation with health-focused buyers. Specialty varieties like amaranth and shiso command premium pricing from chef-driven restaurants.
How much space do I need to grow microgreens in New Brunswick?
A 10 by 10 foot room with two shelving units holds 60 to 80 active trays, which is enough to produce $3,000 to $5,000 per month. A basement, garage corner, spare bedroom, or sunroom all work in New Brunswick's climate. Vertical shelving is the fastest path to higher revenue per square foot.

Commercial proficiency, meaning you can run 50-plus trays per week without losing crops to mold or under-seeding, takes 60 to 90 days. The seed density and watering math is the single biggest predictor of how fast you get there.
Do I need a license to sell microgreens in New Brunswick?
For farmers market and direct-to-consumer sales in New Brunswick, most growers operate under New Jersey's cottage food law with no special license. For wholesale to restaurants and grocery stores, you typically need a basic food handler permit, a sales tax permit, and depending on volume, an inspection from your county health department.

Restaurant wholesale in New Brunswick runs $1.50 to $2.50 per ounce for standard varieties, $3 to $5 per ounce for specialty varieties like shiso, micro basil, or amaranth.
